Description

Die Erfindung betrifft eine Heizungs-, Belüftungs- oder Klimaanlage, insbesondere für ein Kraftfahrzeug, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a heating, ventilating or air conditioning system, in particular for a motor vehicle, according to the preamble of claim 1.

Bei Niederverbrauchsfahrzeugen ist auf Grund des geringen Abwärmeangebots des Motors eine zusätzliche Heizleistung zur Erwärmung des Fahrgastraums sowie zur schnellen Beseitigung eines Beschlags (Eis oder Wasser) insbesondere an der Windschutzscheibe erforderlich. Dazu können in Strömungsrichtung der Luft gesehen nach einem vom Kühlwasser des Fahrzeugmotors durchströmten Wärmetauscher angeordnete Zusatzheizer, zum Beispiel PTC-Heizelemente oder andere, nicht vom Kühlwasser durchströmte Wärmetauscher, wie zum Beispiel ein Zusatz-Wärmetauscher einer CO2-Wärmepumpe, verwendet werden, die etwas beabstandet vom Wärmetauscher im Warmluftkanal angeordnet sind.In low-consumption vehicles due to the low heat output of the engine, an additional heating power to heat the passenger compartment and for quick removal of a fog (ice or water), especially on the windshield is required. For this purpose, viewed in the direction of flow of the air can be used after a flowed through by the cooling water of the vehicle engine heat exchanger additional heaters, for example PTC heating elements or other, not flowed through by the cooling water heat exchanger, such as an additional heat exchanger of a CO2 heat pump, which is slightly spaced are arranged by the heat exchanger in the hot air duct.

Aus der FR 2 798 095 ist als nächster Stand der Technik eine Heizungs- und/oder Klimaanlage für ein Kraftfahrzeug bekannt, welche einen ersten Heizkörper und einen Zusatzheizkörper aufweist, wobei der Zuatzheizkörper in einem Gehäuseteil angeordnet ist, welches vom Hauptgehäuse isolierbar ist, um eine Variante mit und eine Variante ohne Zusatzheizung zu bilden.From the FR 2 798 095 is known as the closest prior art, a heating and / or air conditioning for a motor vehicle having a first radiator and an auxiliary heater, wherein the additional radiator is arranged in a housing part, which is isolatable from the main housing, a variant with and a variant without To form additional heating.

Die strömungstechnische Auslegung der Heizungs-, Belüftungs- oder Klimaanlage, im folgenden zusammenfassend als Klimaanlage bezeichnet, einschließlich des Wärmetauscher und des Zusatzheizers ist jedoch recht aufwändig, da im allgemeinen jedes Heizungs- oder Klimaanlagensystem neu ausgelegt werden muss, einmal unter Berücksichtigung des Zusatzheizers und einmal ohne diesen.However, the fluidic design of the heating, ventilation or air conditioning, collectively referred to as air conditioning, including the heat exchanger and the additional heater is right consuming, since in general any heating or air conditioning system must be redesigned, once taking into account the additional heater and once without this.

Auch kann es nachteilig sein, daß die Luft innerhalb der Klimaanlage eine Vorzugsrichtung in einem Kanal hat und davon abweichend ausgerichtete Kanäle werden nur schwach an- bzw. durchströmt.It may also be disadvantageous that the air within the air conditioning system has a preferred direction in a channel and deviating aligned channels are only weak on or flows through.

Es ist Aufgabe der Erfindung, eine kostengünstige, allgemein verwendbare Heizungs- oder Klimaanlage zur Verfügung zu stellen, die bezüglich der obigen Nachteile zumindest teilweise verbessert sind.It is an object of the invention to provide a low cost, general purpose heating or air conditioning system, which are at least partially improved with respect to the above disadvantages.

Diese Aufgabe wird gelöst durch eine Heizungs- oder Klimaanlage mit den Merkmalen des Anspruchs 1.This object is achieved by a heating or air conditioning system with the features of claim 1.

Erfindungsgemäß ist eine Heizungs- oder Klimaanlage, insbesondere für eine Kraftfahrzeug, vorgesehen, die - anstelle eines Zusatzheizers - ein nicht beheizbares Ersatzelement aufweist, das im Wesentlichen oder bevorzugt exakt die geometrische Gestalt des Zusatzheizers hat. Dabei kann bei der teueren Ausführungsform der Zusatzheizer und bei der billigeren Ausführungsform das Ersatzelement auch etwas beabstandet vom systemübergreifend verwendeten Wärmetauscher angeordnet sein. Ein derartiges Ersatzelement ermöglicht die Verwendung eines strömungstechnisch optimal ausgelegten Wärmetauschers und somit der gesamten Klimaanlage auch in preisgünstigeren Fahrzeugen, ohne dass konstruktive Änderungen an der Heizungs- oder Klimaanlage oder dem entsprechenden Bauraum erforderlich sind. Ferner wird das Schichtungs- und Regelungsverhalten der Heizungs- oder Klimaanlage nicht oder nur unwesentlich geändert. Durch die Stückzahlerhöhung in Folge der gleichen Gehäuseteile können die Produktionskosten deutlich gesenkt werden. Ferner wird der Abstimmungsaufwand für verschiedene Ausgestaltungen (z.B. mit Zusatzheizer und ohne dasselbe) deutlich verringert, wodurch unter anderem auch die Entwicklungszeiten verkürzt und die Entwicklungskosten gesenkt werden können.According to the invention, a heating or air conditioning system, in particular for a motor vehicle, is provided which-instead of an auxiliary heater-has a non-heatable replacement element which essentially or preferably has exactly the geometric shape of the auxiliary heater. In the case of the expensive embodiment, the additional heater and, in the cheaper embodiment, the replacement element may also be arranged somewhat spaced apart from the heat exchanger used throughout the system. Such a replacement element allows the use of a fluidically optimally designed heat exchanger and thus the entire air conditioning in less expensive vehicles without constructive changes to the heating or air conditioning or the corresponding space are required. Furthermore, the layering and control behavior of the heating or air conditioning is not or only slightly changed. By increasing the number of units as a result of the same housing parts, the production costs can be significantly reduced. Furthermore, the coordination effort for various configurations (eg with additional heater and without the same) is significantly reduced, whereby, among other things, the development times can be shortened and the development costs can be reduced.

Als Ersatzelement für den Zusatzheizer ist ein Leitgitter mit verschieden profilierten und angestellten Schaufeln vorgesehen. Diese sind vorzugsweise in horizontaler und vertikaler Richtung angeordnet. Der horizontale und vertikale Abstand der Schaufeln, ihre Anzahl sowie die geometrische Gestaltung der einzelnen Schaufeln sind projektspezifisch und für jedes System neu festzulegen.As a replacement element for the additional heater, a guide grid with differently profiled and employed blades is provided. These are preferably arranged in the horizontal and vertical directions. The horizontal and vertical spacing of the blades, their number and the geometric design of the individual blades are to be project-specific and redefined for each system.

Das Ersatzelement besteht vorzugsweise aus Kunststoff. Dies ermöglicht eine kostengünstige Herstellung.The replacement element is preferably made of plastic. This allows a cost-effective production.

Vorzugsweise ist das Ersatzelement mit einer Abdeckung für einen Schacht für den zu ersetzenden Zusatzheizer ausgebildet, so dass durch die Montage des Ersatzelements keine zusätzlichen Montagekosten anfallen.Preferably, the replacement element is formed with a cover for a shaft for the additional heater to be replaced, so that no additional assembly costs are incurred due to the mounting of the replacement element.

Weiterhin wird die Aufgabe gelöst durch ein Ersatzelement mit den Merkmalen des Anspruchs 8 bei einer Heizungs- oder Klimaanlage, insbesondere für ein Kraftfahrzeug, mit einer Aufnahme- oder Anbringmöglichkeit an einem Wärmetauscher der Heizungs- oder Klimaanlage und/oder benachbart zum Wärmetauscher der Heizungs- oder Klimaanlage und/oder in einem Kanal der Anlage für ein nicht beheizbares Luftleitelement.Furthermore, the object is achieved by a spare element with the features of claim 8 in a heating or air conditioning, in particular for a motor vehicle, with a recording or attachment possibility to a heat exchanger of the heating or air conditioning and / or adjacent to the heat exchanger of the heating or Air conditioning and / or in a channel of the system for a non-heated air guide.

Das Luftleitelement ist durch ein Leitgitter gebildet, wobei das Leitgitter profilierte und angestellte Leitschaufeln aufweist. Bei unterschiedlichen Ausführungsbeispielen kann es vorteilhaft sein, wenn die Leitschaufeln in horizontaler und/oder vertikaler Richtung angeordnet sind.The air guide element is formed by a guide grid, wherein the guide grid has profiled and employed guide vanes. In different embodiments, it may be advantageous if the vanes are arranged in the horizontal and / or vertical direction.

Besonders vorteilhaft ist es, wenn das Luftleitelement aus Kunststoff besteht.It is particularly advantageous if the air guide element consists of plastic.

Besonders vorteilhaft ist es, wenn das Luftleitelement in Luftströmungsrichtung gesehen nach dem Wärmetauscher in einem Warmluftkanal angeordnet ist.It is particularly advantageous if, viewed in the air flow direction, the air guide element is arranged after the heat exchanger in a hot air duct.

Auch kann es vorteilhaft sein, wenn das Luftleitelement mit einer Abdeckung für einen Schacht für das Heizelement ausgebildet ist.It may also be advantageous if the air guide element is formed with a cover for a shaft for the heating element.

Die erfindungsgemäße Aufgabe wird weiterhin gelöst mit einem Baukasten einer Heizungs- oder Klimaanlage, insbesondere für ein Kraftfahrzeug, mit einer Aufnahme- oder Anbringmöglichkeit an einem Wärmetauscher der Heizungs- oder Klimaanlage, daß benachbart zum Wärmetauscher der Heizungs- oder Klimaanlage und/oder in einem Kanal der Anlage für ein nicht beheizbares Luftleitelement oder Luftführungselement angeordnet ist.The object of the invention is further achieved with a modular system of a heating or air conditioning, especially for a motor vehicle, with a recording or attachment possibility to a heat exchanger of the heating or air conditioning, that adjacent to the heat exchanger of the heating or air conditioning and / or in a channel the system is arranged for a non-heated air guide element or air guide element.

Erfindungsgemäß ist das Luftleitelement durch ein Leitgitter gebildet, wobei das Leitgitter profilierte und angestellte Leitschaufeln aufweist. Bei einer Weiterbildung kann es zweckmäßig sein, wenn die Leitschaufeln in horizontaler und vertikaler Richtung angeordnet sind. Die Leitschaufeln wären vorteilhaft in Luftanströmungsrichtung betrachtet gekrümmt ausgebildet, so daß sie eine Umlenkung des Luftstroms zumindest teilweise bewirken können.According to the invention the air guide element is formed by a guide grid, wherein the guide grid has profiled and employed guide vanes. In a further development, it may be expedient if the guide vanes are arranged in the horizontal and vertical directions. The guide vanes would advantageously be considered curved in the direction of air flow, so that they can at least partially effect a deflection of the air flow.

Vorteilhaft ist es, wenn das Leitgitter von einem Rahmen oder zumindest zwei benachbarten Schienen umfaßt ist, welcher bzw. welche in eine Aufnahme in einem Gehäuse einer Klimaanlage aufnehmbar ausgebildet ist. Die Leitschaufeln wären dann vorzugsweise zumindest teilweise zwischen den Schienen oder innerhalb des Rahmens angeordnet.It is advantageous if the guide grid is encompassed by a frame or at least two adjacent rails, which is designed to be receivable in a receptacle in a housing of an air conditioning system. The vanes would then preferably be at least partially disposed between the rails or within the frame.

Vorteilhaft ist, wenn das Luftleitelement aus Kunststoff besteht.It is advantageous if the air guide element consists of plastic.

Besonders vorteilhaft ist es, wenn das Luftleitelement in Luftströmungsrichtung gesehen nach dem Wärmetauscher, wie Verdampfer oder Heizkörper oder Zusatzheizer, in einem Warmluftkanal und/oder einem Kaltluftkanal angeordnet ist.It is particularly advantageous if, as seen in the air flow direction, the air guide element is arranged downstream of the heat exchanger, such as evaporator or radiator or additional heater, in a hot air duct and / or a cold air duct.

Besonders vorteilhaft ist es, wenn das Luftleitelement mit einer Abdeckung für einen Schacht für das Heizelement ausgebildet ist.It when the air guide is formed with a cover for a shaft for the heating element is particularly advantageous.

Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen im Einzelnen erläutert. Dabei zeigt:

Figur 1
eine Klimaanlage im Schnitt,
Figur 2
eine Ersatz- oder Luftleitelement und
Figur 3
eine Ersatz- oder Luftleitelement.
The invention will be explained in detail below on the basis of exemplary embodiments. Showing:
FIG. 1
an air conditioning on average,
FIG. 2
a spare or spoiler element and
FIG. 3
a replacement or air deflector.

Gemäß einem Ausführungsbeispiel zeigt Figur 1 eine Heizungs- oder Klimaanlage 1 mit einem Gebläse 2 und einem dem Gebläse nachgeschalteten Kanal, durch den Luft von dem Gebläse 1 einem Verdampfer 3 zugeführt wird. Die Luft tritt durch den Verdampfer und kann nach dem Verdampfer 3 mittels einer nicht dargestellten Mischklappe aufgeteilt werden auf einen Kaltluftkanal 6c und/oder einen Warmluftkanal 6a,6b.According to one embodiment shows FIG. 1 a heating or air conditioning system 1 with a fan 2 and a downstream of the fan duct through which air from the fan 1 to an evaporator 3 is supplied. The air passes through the evaporator and can be divided after the evaporator 3 by means of a mixing flap, not shown, on a cold air duct 6c and / or a hot air duct 6a, 6b.

Die Luft, die durch den Warmluftkanal 6a,6b strömt (Pfeil A), durchströmt einen Heizkörper 4 und anschließend einen Zusatzheizkörper 5 oder durch ein Ersatzelement oder Luftleitelement.The air flowing through the hot air duct 6a, 6b (arrow A), flows through a radiator 4 and then an auxiliary heater 5 or through a replacement element or air guide.

Bei der teueren Variante einer Heizungs- oder Klimaanlage ist ein Wärmetauscher mit einem getrennt hiervon ausgebildeten Zusatzheizer, im Folgenden als Heizelement bezeichnet, vorgesehen, der z.B. durch einen Zusatz-wärmetauscher einer CO2-Wärmepumpe, ein PTC Element oder ein anderes Heizelement gebildet wird. Das Heizelement ist im Warmluftkanal 6a,6b in Luftströmungsrichtung gesehen nach dem Wärmetauscher 4 angeordnet.In the expensive version of a heating or air conditioning system, there is provided a heat exchanger with an auxiliary heater formed separately therefrom, hereinafter referred to as a heating element, which is e.g. is formed by an additional heat exchanger of a CO2 heat pump, a PTC element or another heating element. The heating element is arranged in the hot air duct 6a, 6b in the air flow direction after the heat exchanger 4.

Gemäß einer anderen Ausführung kann das Luftleitelement auch in einem Kaltluftkanal (Pfeil B) angeordnet sein, was jedoch in Figur 1 nicht dargestellt ist.According to another embodiment, the air guiding element can also be arranged in a cold air duct (arrow B), which, however, is described in US Pat FIG. 1 not shown.

Bei der billigen Variante wird an Stelle des Heizelements ein Ersatzelement 5 vorgesehen, das im Wesentlichen die gleichen strömungstechnischen Eigenschaften aufweist, wie das Heizelement, wobei es sich vorliegend um ein Leitgitter mit verschieden profilierten und angestellten Schaufeln handelt.In the cheap version, a replacement element 5 is provided instead of the heating element, which has substantially the same fluidic properties, such as the heating element, which in the present case is a guide grid with differently profiled and employed blades.

Somit kann auch für die Variante ohne Zusatzheizer ein optimiertes Strömungsverhalten, das heißt Regelverhalten, Schichtung und Luftverteilung, erreicht werden, wobei die gleichen Gehäuseteile und sonstigen Einbauten verwendet werden, wie für die Variante mit Zusatzheizer.Thus, even for the variant without additional heater optimized flow behavior, that is, control behavior, stratification and air distribution, be achieved, with the same housing parts and other installations are used, as for the variant with additional heater.

Nach dem Element 5 wird die Luft in der Kammer 9 gegebenenfalls gemischt und verteilt und zu Auslässen 7 oder 8 geführt.After the element 5, the air in the chamber 9 is optionally mixed and distributed and fed to outlets 7 or 8.

Die Figuren 2 und 3 zeigen ein Ersatzelement oder ein Luftleitelement, das statt eines Zusatzheizers in ein Gehäuse einer Klimaanlage eingesetzt werden kann. Auch kann ein solches Luftleitelement zur Luftverteilung in ein Gehäuse oder in einen Kanal einer Klimaanlage eingesetzt werden.Figures 2 and 3 show a replacement element or an air guide element, which can be used instead of an auxiliary heater in a housing of an air conditioner. Also, such an air guide for air distribution in a housing or in a channel of an air conditioner can be used.

Das Element 5 der Figuren 2 und 3 weist einen Rahmen 50 auf, der in eine Aufnahme eines Gehäuses einsetzbar ist. Ist das Element 5 als Ersatzelement für einen nicht eingesetzten Zusatzheizer vorgesehen, ist es zweckmäßig, wenn das Element die gleichen äußeren Abmessungen wie das zu ersetzende Heizelement aufweist.The element 5 of Figures 2 and 3 comprises a frame 50 which is insertable into a receptacle of a housing. If the element 5 is provided as a replacement element for an unused auxiliary heater, it is expedient if the element has the same outer dimensions as the heating element to be replaced.

In den Figuren 2 und 3 ist zu erkennen, daß innerhalb des umlaufenden Rahmens 50 ein Leitgitter 51 mit senkrechten und waagrechten Stegen 52,53 gebildet ist. Das Leitgitter 51 weist dabei profilierte und angestellte Leitschaufeln 54 auf. Diese Leitschaufeln können dabei in horizontaler und/oder vertikaler Richtung angeordnet sein. Vorzugsweise ist das Ersatzelement aus Kunststoff hergestellt, wie durch ein Spritzgußverfahren.In the figures 2 and 3 it can be seen that within the circumferential frame 50, a guide rail 51 is formed with vertical and horizontal webs 52,53. The guide grid 51 has profiled and set guide vanes 54. These vanes can be arranged in the horizontal and / or vertical direction. Preferably, the replacement element is made of plastic, such as by an injection molding process.

Das Element weist einen Ansatz 60 auf, der an einer Seite des Elements angeordnet ist. Dieser Ansatz bildet eine Abdeckung für einen Schacht im Gehäuse der Klimaanlage, wenn das Element in die Anlage eingesetzt ist. Vorzugsweise weist der Ansatz einen umlaufenden Rand auf, an dem auch Dichtmittel vorgesehen sein können, um das Gehäuse abzudichten.The element has a lug 60 disposed on one side of the element. This approach forms a cover for a shaft in the housing of the air conditioner when the element is inserted into the system. Preferably, the approach to a peripheral edge on which sealing means may be provided to seal the housing.
